Additional Information
Statement
Reference

Drives expression in about 80% of adult olfactory receptor neurons, and in antennal glomeruli with the exception of VM1 and DP1m.

(FlyBase Curators, 2017)

ScerGAL4Orco.2.642.HsimVP22 drives expession in adult olfactory receptor neuron Or83c (ai2a neuron).

(Ronderos et al., 2014)

Expression is observed in about 70% of olfactory receptor neurons.

(Tanoue et al., 2004)

Expression is observed in about 80% of olfactory neurons, but not in GR21A+ neurons.

(Suh et al., 2004)

ScerGAL4Or83b.2.642.T:HsimVP22 is estimated to express in approximately 80% of all olfactory receptor neurons.

(Suh et al., 2004)

Adult expression is observed in 80% of olfactory neurons, and in antennal glomeruli with the exception of VM1 and DP1m.
